QUESTION
As we know, xv6 doesn't let a spinlock be acquired twice (even by a process itself).
I am trying to add this feature which lets a process to acquire a lock more than once.
In order to reach this, I am adding an attribute called lock_holder_pid
to the struct spinlock
which is supposed to hold the pid of the process which has acquired this lock.
The only file I have changed is spinlock.c
Here is my new acquire()
function:
ANSWER
Answered 2021-Jun-10 at 09:15This is simply because you are trying to have access to a field of a null struct (myproc()->pid
).
As you may know, myproc()
returns a process running on the current processor. If you look at main.c
, you may notice that the bootstrap processor starts running there. Therefore, if we can find a function which calls the acquire()
function before setting up the first process, the problem will be solved.
If you take a close look at the kinit1
function, you can realize that the acquire
function is called in it. Consequently, we found a function that uses the acquire
function, even before initializing the ptable
struct. Therefore, when you try to access the myproc()
value, it is not initialized yet.

QUESTION
I created custom SpinLock class
I want to use this class in condition variable, but have an error
...ANSWER
Answered 2021-Jun-06 at 17:46std::condition_variable
only supports std::unique_lock
. Use std::condition_variable_any
instead.
The
condition_variable_any
class is a generalization ofstd::condition_variable
. Whereasstd::condition_variable
works only onstd::unique_lock
,condition_variable_any
can operate on any lock that meets theBasicLockable
requirements.

Current output is
...ANSWER
Answered 2021-Jun-06 at 09:17curNum_
needs to be protected by mutex or we can simply switch to an atomic number, then spawn 2 threads in the constructor to call even
odd
respectively, the output is what you expected.
For the call member function in the thread, we don't need a static function, just capture this
will be fine.
We don't need the last return;
statement, so I removed it.
Tips:
Thread sanitizers will help your stay from data races.
